Ares told Diana that he had been imprisoned by the other Gods of Olympus and bound in chains that were secured by Aphrodite through the power of her love. He also told her that years ago, Phobos and Deimos had implanted false memories of Themyscira into her mind, and these had caused her to imagine aspects of her past that had never happened in reality. Meanwhile, Phobos and Deimos entered Themyscira and battled with the Amazons. Diana knew what she had to do, and called Ares to unite her with Phobos and Deimos. He teleported them to her, and using her Lasso of Truth, Wonder Woman bound them through the power of her unconditional love for them, as Aphrodite had done to Ares. With the twin gods defeated, Diana attempted to leave Ares' prison along with Veronica and Izzy, however Izzy's essence had been attached to the realm and could not return to Earth. Izzy was forced to either live out the rest of her days in the prison or live in Themyscira as an Amazon for eternity. She chose the latter and Veronica said goodbye to her daughter. Diana was briefly reunited with her mother, for the first time since she left the island.
In all three films Diana has been in, she is never referred to as "Wonder Woman". Likewise, the alias isn't seen anywhere in print either. The closest it has come is the logo used in Lex Luthor's data, being two "W"s. Likewise, Bruce Wayne is only called "Batman" three times in the run of the DCEU. Once by Perry White, once by Barry Allen, and once by Aquaman.
While Superman watched out for Zod, Diana visited the deserted Themyscira to speak to her mother, still a clay statue. In her absence, a demon from Tartarus had escaped from its prison and roamed free on the island. Wonder Woman destroyed the creature and sealed the gates to Tartarus with her lasso. Leaving the island, she received word from Batman that Superman was engaging Zod and Faora in battle. Reaching Superman’s side, Wonder Woman steadily overwhelmed Faora until Zod threatened Superman’s life. Wonder Woman was forced to let the criminals go.
Some men were unhappy with women-only screenings held at the Alamo Drafthouse Cinema in Austin, with some opponents of the gender-restricted screening stating on platforms such as Facebook that such screenings were discriminatory against men. A gay Albany Law School professor initiated a complaint with Austin's Equal Employment and Fair Housing Office claiming discrimination against male prospective customers and employees of the theater. The chain responded with an online statement saying the event "may have created confusion—we want everybody to see this film" and announced a similar event at their Brooklyn location. Tickets sold out in less than an hour, prompting the chain to schedule additional screenings. On July 18, Alamo Drafthouse proposed settlement offers of a Wonder Woman DVD to the complainants, stating "Respondent did not realize that advertising a 'women's only' screening was a violation of discrimination laws."
On occasions Wonder Woman has employed a magical sword of unknown (though presumably Amazon) origin. This sword has been used most specifically against those with the power of invulnerability as invulnerability generally does not work against magical items. It is generally represented as a short sword. In Wonder Woman (vol. 4) #15, Hephaestus modifies Diana's bracelets so that she can manifest two short swords from them during battle.
Wonder Woman and the other heroes were finally released from the Firestorm Matrix when Batman used the Lasso of Truth on Firestorm. Superman was still infected with the Kryptonite shard inside his nervous system, but Lex Luthor was able to extract it, saving Superman's life. Luthor also assembled a group of villains that defeated the Crime Syndicate. Later, at the Batcave, Wonder Woman and the Justice League talked about the enemy that destroyed the Crime Syndicate's world and came to the conclusion that Darkseid would return.
